AUTOMATIC FAN.

Specification of Letters Patent.

Patented Mar. 21, 1916.

To all whom it may concern:

Be it known that 1, HONOR F. CRYAR, a citizen of the United States, residing at De Bidder, in the parish of Beauregard and State of Louisiana, have invented new and useful Improvements in Automatic F ans, of which the following is a specification.

This invention relates to automatic fans and has particular reference to a spring operated fan.

The object of the present invention is the provision of a fan of this character, which is simple in construction, durable and efficient in its purpose and embodying a novel construction of means for oscillating the same.

Other objects will appear as the following description is read in connection with the accompanying drawing in which:

Figure 1 is a longitudinal sectional view. Fig. :2 is a rear elevation. Fig. 3 is a horizontal sectional view.

Like numerals of reference indicate simi lar parts throughout the several views.

Referring more particularly to the drawing 5 designates a base from the rear edge of which rises a substantially L-shaped bracket 6. The base and short arm 7 of the vL-shaped bracket are provided with alined sockets for the reception of thecone-shaped bearings 8 formed on the casing 9, in which is arranged the operating mechanism of the fan. The operating or clock-like mechanism is mounted in a frame comprising spaced parallel members 10 connected by the cross bars 11.

Journaled between the members 10 of the frame is a shaft 12 having fixed thereto the spring operated gear 13 controlled by the escapement mechanism 14 of usual con struction, which is connected therewith by a train of gear wheels 15 of the proper size to obtain the required speed. Mounted upon one end of the main shaft 27 is a drive wheel 16 over which and the pulley 17 rides the belt 18, to drive the shaft 19 to which the pulley 17 is fixed. Mounted on the shaft 19 is a gear wheel 20 meshing with the pinion 21 upon the shaft 22, the latter having fixed thereto a gear wheel 23 which in turn meshes with a pinion 24 on the fan shaft 25, which projects through the front wall of the casing, the latter having fixed thereto a balance wheel 26. The number and size of these gears may also be varied to regulate the speed of the fan.

Projecting from the rear of the casing 9 is the shaft 27 of one of the train of gear wheels 12, the shaft being eccentrically connected as at 28 to the wheel 29, the latter being mounted for rotation within the central vertically disposed oblong opening 30 formed in the L-shaped bracket arm 6, the opposite side portions of the latter being substantially U-shaped in cross section as shown. By reason of this construction it will be obvious that as the wheel 29 rotates within the opening 30 the fan casing with its contents will be caused to oscillate from side to side. The rear wall of the casing is provided with a key-hole opening to permit the insertion of a suitable key for winding the motor when necessary.

it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent without requiring a more extended explanation and therefore the same has been omitted.

\Vhat I claim is An automatic fan comprising a base, a substantially L-shaped bracket rising from one edge thereof and having its short arm disposed in spaced parallel relation thereabove, a fan casing supported between said arm and base for oscillatory movement, the long arm of said bracket having a vertically disposed oblong opening therein, a cam mounted for rotation within said opening, a spring operated motor arranged within the casing, and a shaft projecting from within the casing and connected with the motor and said cam for rotating the latter within said opening whereby oscillatory movement is imparted to said casing.

In testimony whereof I atliX my signature in presence of two witnesses.

HONOR F. CRYAR.
